Will allow more precision in compatible games

Accessory maker MOGA has formally revealed the Ace Power, a game controller for the iPhone and iPod touch. The device is the first to take advantage of iOS 7's GameController API, standardizing controller support. It includes two sticks, a direction pad, four main buttons, and shoulder triggers. It clamps around the top and bottom of an iPhone or iPod, also plugging into the Lightning port. This lets the accessory supply extra battery life.

The Ace Power costs $99, and will launch tomorrow at Apple's online and retail stores, as well as MOGA's website. The product should be just the first in a wave of iOS 7 controllers; companies like Logitech and ClamCase have also hinted at upcoming products, and details have occasionally been leaked to the public.
